Four million infant car seats made by an Ohio company have defective handles that can cause serious injuries to babies, federal safety regulators have warned.
R9C PLN hiPSC-CMs display a blunted β-agonist response and defective calcium handling.
Workplace factors may include inadequate workplace design, improper or defective material handling equipment, improper manual or mechanical handling methods, and inadequate training.
We next examined whether the rescue of mitochondrial morphology could ameliorate the defective Ca2+ handling capacity of Afg3l2 −/− cells.
Thus, there appears to be a tight connection between disrupted t-tubule structure and defective Ca2+ handling.
Our results show that the defective Ca2+ handling in Afg3l2 −/− cells is caused by fragmentation of the mitochondrial network, secondary to respiratory dysfunction and the consequent processing of OPA1.
As intracellular calcium is required also for eNOS [ 106] and NADPH oxidase activation [ 107], it seems plausible that defective calcium handling or signaling in the endothelium [ 108], resulting in abnormal calcium accumulation, might account for the acceleration of EDCFs production resulting in ED.
The RBM20-iPSC-CMs showed abnormal distribution of sarcomeric α-actinin and defective calcium handling compared to control-iPSC-CMs, suggesting disorganized myofilament structure and altered calcium machinery in CMs of the RBM20 patient.
Defective calcium handling, hyperaldosteronism, and RV-PA uncoupling herald the onset of overt right ventricular failure [ 26].
The presence of LB-like structures in sPD cybrids suggests that mitochondrial dysfunction associated with defective protein handling may account for PD pathogenesis.
